Eurofins EAG Laboratories (EAG) Scientists Dr. Charles W. Magee and Dr. Temel H. Buyuklimanli recently published a paper that was recently presented at a lecture during the 23rd International Conference on SIMS held in Minneapolis (September 2022).
The paper, entitled “Secondary Ion Mass Spectrometry Quantification: Do You Remember When a Factor of 2 Was Good Enough”, focuses on the early days of SIMS quantification and its evolution throughout the years. It also dives into how EAG tackled the problem of quantification of both major and minor elements in nonuniform, multi-element matrices with continuously graded composition changes using Point-by-point CORrected-SIMS – or PCOR-SIMS.
The paper is included in the special topic collection of papers around the subject “CHIPS: The Future of Semiconductor Processing and Devices”. This collection of papers are relevant to the CHIPS Act passed by Congress.
Rare earth magnets power some of today’s most advanced technologies. Part 3 of this series explores how the magnets are produced, challenges of maintaining purity at every step, and why precision analysis is essential for building a reliable supply chain.

Minerology was one of the earliest fields to benefit from X-ray Diffraction (XRD). Prior to XRD, minerals could only be identified by their external symmetry, shape, and color. XRD transformed mineral identification into an exact science, being perfect for characterizing crystalline materials by their internal structure, not just external appearance.
